Expand description

DynamicSamplingContext created by the first Sentry SDK in the call chain.

Because SDKs need to funnel this data through the baggage header, this needs to be representable as HashMap<String, String>, meaning no nested dictionaries/objects, arrays or other non-string values.

Fields§

§trace_id: Uuid

ID created by clients to represent the current call flow.

§public_key: ProjectKey

The project key.

§release: Option<String>

The release.

§environment: Option<String>

The environment.

§transaction: Option<String>

In the transaction-based model, this is the name of the transaction extracted from the transaction field in the starting transaction and set on transaction start, or via scope.transaction.

In the spans-only model, this is the segment name for the segment that started the trace.

§sample_rate: Option<f64>

The sample rate with which this trace was sampled in the client. This is a float between 0.0 and 1.0.

§user: TraceUserContext

The user specific identifier (e.g. a user segment, or similar created by the SDK from the user object).

§replay_id: Option<Uuid>

If the event occurred during a session replay, the associated replay_id is added to the DSC.

§sampled: Option<bool>

Set to true if the transaction starting the trace has been kept by client side sampling.

§other: BTreeMap<String, Value>

Additional arbitrary fields for forwards compatibility.
